PHOTOGRAPHIC WASHING APPARATUS.

' SPECIFICATION forming part of Letters Patent No. 628,917, dated July 18, 1899.

I Application filed December 1'7, 1898. Serial No.699,565. (No model.)

To all whom it may concern:

Be it known that I, CHARLES W. BLoDoET, a citizen of the United States, residing in New York, borough of Manhattan, State of New York, have invented certain new and useful Improvements in Apparatus for W'ashing Photographic Negatives and Prints, of which the following is a specification.

The object of my invention is to provide a convenient and efficient device wherein a number of films, prints, or plates may be washed at the same time and each have an independent water supply and discharge, and wherein the operator may readily tell when the proper washing of the films and prints is completed.

In the accompanying drawings, which show my invention embodied in a convenient and practical form, Figure 1 is an elevation in perspective, partly broken away; Fig. 2, a detail sectional view therethrough; Fig. 3, a section on the line 3 3 of Fig. 4; and Fig. 4., a front elevation, Figs. 3 and 4 showing a modified'construction.

'In the device as I have elected'to illustrate it in Figs. 1 and 2 and as I prefer to make it on account of convenience and compactness of structure the trays to contain the negatives are arranged in a single vertical series.

The apparatus consists of a casing or tray support which may have a solid bottom, a solid back, and two opposite solid sides. The

front and top may be open, as shown. Along the sides I arrange a series of ledges a, forming guides or slideways for the reception or support of the trays Z). In one of the inner corners of the casing is a vertical water-pipe c, which extends down to the bottom of the casing and then turns upwardly. From the latter portion extend a series of nipples cl, one for each tray or receptacle, so arranged, as shown, that the nipple projects over the edge of the tray that may be placed immediately beneath it. Each nipple is preferably closed at its end and formed with an outlet (1' on its under side near its end, so that the water is discharged downwardly into the corner of the tray. The hf' hest nipple in the series is the longest, the neJt one below somewhat shorter, and so 011 throughout the entire series. Stopsf in each slideway may be provided to liinit the inward movement of the tray, so that the top tray shall project farther from the casing or support than the next one below it, and so on throughout the series, as indicated in the drawings. In each case, however, when the tray is slid into the limit of its movement its inner edge passes under the discharge-orifice of its nipple. The bottom of the casing on each side of the corner occupied by the water-pipe hasfeet or projections g, which give the apparatus such a tilt or inclination that the water entering the inner corner of thepan will overflow di agonally at the opposite outer corner. The top of the water-pipe may have attached to it a rubber tube communicating with a wator-supply, or a funnel may be connected therewith and water supplied to the funnel by a pipe, faucet, or otherwise. The trays,

each with a negative or print therein, may

be placed in position and the water turned on. The discharge from the corner of each tray runs to waste without falling into any tray beneath it, and the operator may therefore tell at a glance by the color of the discharge from each tray when the film orprint therein is sufficiently washed. With the V arrangement shown if it is only desired to wash one s print or negative the bottom tray alone may be used and only sufficient water admitted to the stand-pipe to supply the lowest nipple.

In Figs. 3 and 4: a modified construction is shown wherein more than one tray is arranged in the same horizontal plane, two vertical series being shown. Inthis construction the stand-pipe 0 may be arrangedcentrally at the rear of the casing and have two rising branches 0 c, and each may have in it a cook or valve 0 Each rising branch 0 has connected to and supported by it a series of horizontal discharge-pipes 0 arranged at different distances from it and having distrays, a waterpipe having a series of independent outlets, one for each tray and-tho trays being arranged so that the water overflowing from one tray does not enter any of the other trays.

2. In a photographic plate orprint washing apparatus, the combination of a casing or sup port having a series of vertically-arranged slideways, each adapted to receive an independentlyremovable tray, a water-supply pipe having a series of water-discharge nipples one for each tray, the organization being such that the top tray projects from the casing farther than the one beneath it and so on through the entire series,substantially as and for the purpose set forth.

3. A photographic plate or print washing apparatus comprising a casing with a vertical series of slideways for the reception of trays, a Water stand-pipe located within the casing at one corner thereof and having laterally-projecting nipples of graduallydecreasing length from the top nipple to the lowest one, whereby trays of the same length may be arranged so that the upper one will project from the casing farthcrthan the one beneath it and so on throughout the entire series.

4. In a photographic plate or print washing apparatus, a casing having a vertical series of slideways for the reception of trays, a stand-pipe arranged at an inner corner of the casing and having a series of dischargenipples, one for each tray, the nipples of the series being of gradually-decreasing length from the top downwardly, and the casing being inclined downwardly from the stand-pipe toward the diagonally opposite corner, sub

stantially as and for the purpose set forth.

5. A plate or print washing apparatus having a casing with means for supporting a series of trays so that the overflow from one does not enter another and means for supplying water to'each tray individually.

In testimony whereof I have hereunto subscribed myname.
